Back2Fronts is an extensive mod that will overhaul your Call of Duty 2 game to a next level. This mod brings more variety, intensity, realism and battle-like experience. Try new weapons, fight new enemies, fulfil new missions and explore new options. Mod is SP and MP friendly (although primary part is SP).
This video shows testing reworked older models in CoD2 - Tokarev AVT-40 (unscoped) and SVT-40 (scoped). The main point is the final animation that includes 3D sniper reticle and empty/not-empty reload.
